+## :book: Rule Details
+
+This rule disallows the use of v-text / v-html on component.
+
+If you use v-text / v-html on a component, it will overwrite the component's content and may break the component.
+
+<eslint-code-block :rules="{'vue/no-v-text-v-html-on-component': ['error']}">
+
+```vue
+<template>
+  <!-- ✓ GOOD -->
+  <div v-text="content"></div>
+  <div v-html="html"></div>
+  <MyComponent>{{content}}</MyComponent>
+
+  <!-- ✗ BAD -->
+  <MyComponent v-text="content"></MyComponent>
+  <MyComponent v-html="html"></MyComponent>
+</template>
+```
+
+</eslint-code-block>

+## :wrench: Options

+Nothing.
